The ABC Company is considering acquiring an automatic screwing machine for its assembly operation of a product. Three different models with varying automatic features are under consideration. The required investments are $360,000 for model A, $380,000 for model B, and $405,000 for model C. All three models are expected to have the same service life of eight years. The financial information from Table 1, in which model (B-A) represents the incremental cash flow determined by subtracting model A’s cash flow from Model B’s, is available. If the firm’s MARR is 12%, which model should be selected? 

could you give me a comprehensive answer? thank you！
